[0037] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0040] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0041] refer to Figure 1-4 An embodiment of the present invention shows a lamp with a quickly replaceable lamp tube, comprising a lamp holder 1 and a lamp tube module 2; the lamp holder 1 is provided with a first connecting portion 11 and a second connecting portion 12, and the first connecting portion 11 is provided with a first conductive portion 13; the lamp tube module 2 is provided with a third connecting portion 21 and a fourth connecting portion 22, and the third connecting portion 21 is provided with a second conductive portion 23, the third connecting portion 21 forms a snap connection with the first connecting portion 11, and the fourth connecting portion 22 forms a magnetic adsorption connection with the second connecting portion 12; when the third connecting portion 21 forms a snap connection with the first connecting portion 11, the first conductive portion 13 forms an electrical connection with the second conductive portion 23.

[0042] Among them, the snap connection formed between the third connecting part 21 and the first connecting part 11 enables the lamp tube module 2 to be easily and firmly installed on the lamp holder 1. This design does not require the use of additional tools or complicated operations. The user only needs to simply align the lamp tube module 2 with the lamp holder 1 and press it lightly to complete the installation. The magnetic adsorption connection between the fourth connecting part 22 and the second connecting part 12 not only further ensures the stability of the lamp tube module 2, but also provides additional convenience. Even in narrow or hard-to-reach spaces, users can easily position the lamp tube module 2 in the correct position through magnetic attraction, greatly simplifying the replacement process. The combination of the snap connection and the magnetic adsorption connection makes the lamp tube module 2 more firmly on the lamp holder 1 and not easily loosened due to vibration or external force. This not only extends the service life of the lamp tube, but also reduces the safety hazards caused by loosening.

[0043] Specifically, the lamp tube module 2 includes an outer tube 24 and a light source assembly disposed within the outer tube 24. The light source assembly is electrically connected to the second conductive portion 23. Correspondingly, the lamp holder 1 should be provided with a power connection circuit electrically connected to the first conductive portion 13. Conventionally, the lamp can be powered by conventional power supply methods such as mains electricity and batteries. When the first conductive portion 13 is electrically connected to the second conductive portion 23, the light source assembly is electrically connected to the power connection circuit on the lamp holder 1.

[0044] In this embodiment, Figure 1 and Figure 2 The lamp shown is a chandelier. A canopy cover module 3 is connected to a lamp holder 1. The canopy cover module 3 is a decorative or functional component at the top of the chandelier, used to cover the chandelier's wiring, hooks, or other internal structures. Electrical appliances such as a driver can also be installed inside the canopy cover module 3.

[0045] In some embodiments, as Figure 3-6 As shown, the first connecting part 11 includes a first socket 111, and the side wall of the first socket 111 is provided with a card block that can be moved along its radial direction. The first conductive part 13 is a positive contact and a negative contact arranged in the first socket 111; the third connecting part 21 includes a first plug 211 for inserting into the first socket 111, and the outer wall of the first plug 211 is provided with a card slot 212 for the card block to be inserted into; the second conductive part 23 is a positive contact and a negative contact arranged at the end of the first plug 211, and the interior of the first plug 211 is connected to the interior of the outer tube 24.

[0046] In this embodiment, the first plug 211 is arranged on the side of the outer tube 24, and a channel (not marked in the figure) is provided inside the first plug 211 to realize the connection between the light source assembly in the outer tube 24 and the second conductive part 23; the first plug 211 and the outer tube 24 can be fixedly connected by integral molding, bonding, ultrasonic welding, etc.; wherein, the first plug 211 is inserted into the first jack 111, and the card block is inserted into the card slot 212, so that the first plug 211 cannot be separated from the first jack 111 without sufficient external force, thereby realizing a stable connection between the first connecting part 11 and the second connecting part 12.

[0047] More specifically, if Figure 5 and Figure 6As shown, the first connection portion 11 also includes a first mounting cavity 114 formed on the lamp holder 1. An isolation seat 113 is provided in the first mounting cavity 114. The first insertion hole 111 is formed on the isolation seat 113. A ball screw 112 is threadedly connected to the isolation seat 113. A steel ball (not marked in the figure) on the ball screw 112 serves as the clamping block. The ball screw 112 has a spring inside that can push the steel ball. The specific structure of the ball screw can refer to the existing technology. In this embodiment, the ball screw is threadedly connected to the isolation seat 113. By adjusting the position of the ball screw, the clamping force of the ball screw on the first plug 211 can be adjusted, thereby adjusting the force required by the user to insert / remove the first plug 211.

[0048] The isolation seat 113 is made of non-conductive material, such as plastic; Figure 5 As shown, in this embodiment, the first conductive part 13 is fixed on the isolation seat 113 by screws, and the isolation seat 113 is fixed in the first mounting cavity 114 by screws. The isolation seat 113 can separate the first conductive part 13 from the inner wall of the lamp holder 1 to avoid leakage.

[0049] Preferably, if Figure 4-6 , the first connecting portion 11 also includes a first buffer pad 115, at least part of which protrudes from the outer surface of the lamp holder 1. When the third connecting portion 21 forms a snap connection with the first connecting portion 11, the outer tube 24 abuts against the first buffer pad 115. Conventionally, the lamp holder 1 uses a harder material to maintain the stability of the structure, such as metal or hard plastic; and the outer tube 24 uses a light-transmitting material. In this embodiment, the first buffer pad 115 can separate the outer tube 24 from the outer wall of the lamp holder 1 to prevent the outer tube 24 from directly contacting the outer wall of the lamp holder 1, thereby preventing the lamp holder 1 from scratching the outer wall of the outer tube 24 and affecting the light transmission effect. In addition, when encountering vibration, the first buffer pad 115 can provide a buffering effect for the lamp module to protect the lamp module.

[0050] Preferably, if Figure 5 and Figure 6 As shown, the outer tube 24 has a cylindrical outer profile, and the first buffer pad 115 is formed with an arcuate contact surface (not labeled) that matches the outer profile of the outer tube 24. This arcuate contact surface further improves the stability of the outer tube 24 abutting against the first buffer pad 115 and prevents vibration of the outer tube 24. In this embodiment, when the first connecting portion 11 and the third connecting portion 21 form a snap-fit ​​connection, a press fit is formed between the outer tube 24 and the first buffer pad 115, that is, the outer tube 24 is tightly pressed against the first buffer pad 115.

[0051] In some embodiments, as Figure 4 and Figure 7 As shown, the second connecting part 12 includes a second socket 121, and a first adsorption part 122 is provided in the second socket 121; the fourth connecting part 22 includes a second plug 221 for inserting into the second socket 121, and a second adsorption part 222 is provided at the end of the second plug 221; wherein, the first adsorption part 122 and the second adsorption part 222 may both be magnetic parts; or one of the first adsorption part 122 and the second adsorption part 222 is a magnetic part, and the other is a metal part.

[0052] Specifically, the second plug 221 is inserted into the second socket 121 to prevent the fourth connection part 22 from shaking on the lamp holder 1. The second connection part 12 adsorbs the second adsorption part 222 on the fourth connection part 22 through the first adsorption part 122, which can prevent the second plug 221 from being separated from the second socket 121 without external force.

[0053] Specifically, in order to facilitate the arrangement of the first adsorption member 122, as shown in FIG. Figure 7 As shown, the second connecting portion 12 also includes a second mounting cavity formed on the lamp holder 1. A fixing seat 123 is provided in the second mounting cavity. The fixing seat 123 presses the first adsorbent 122 into the second mounting cavity. The second insertion hole 121 is formed on the fixing seat 123. In this embodiment, the first adsorbent 122 is an iron sheet. The fixing seat 123 is connected to the internal structure of the second mounting cavity by screws. The fixing seat 123 presses the first adsorbent 122 into the second mounting cavity. The second adsorbent 222 is a magnet fixed to the end of the second plug 221. The second plug 221 and the outer tube 24 can be fixedly connected by integral molding, bonding, ultrasonic welding, or other methods.

[0054] Preferably, the second connecting portion 12 further includes a second buffer pad 124. At least a portion of the second buffer pad 124 protrudes from the outer surface of the lamp holder 1. When the fourth connecting portion 22 and the second connecting portion 12 form a magnetic connection, the outer tube 24 abuts against the second buffer pad 124. The function of the second buffer pad 124 is the same as that of the first buffer pad 115 described above, and therefore will not be described in detail.

[0055] In some embodiments, as Figure 6 and Figure 8As shown, the lamp tube module 2 also includes a structural bar 251, a lamp tube inner cover 26, a rubber plug 27 and a lamp tube outer cover 28. The structural bar 251 is arranged inside the outer tube 24. The light source assembly is an LED light bar 25 arranged on the structural bar 251. The lamp tube outer cover 28, the rubber plug 27 and the lamp tube inner cover 26 are arranged at the ends of the structural bar 251 in sequence. The lamp tube inner cover 26 is arranged inside the outer tube 24. The lamp tube outer cover 28 is located outside the outer tube 24, and the lamp tube outer cover 28 abuts against the end of the outer tube 24.

[0056] The structural bar 251 serves to provide a mounting structure for the LED light strip 25. The structural bar 251 can be a rod, and multiple LED light strips 25 can be provided, each of which can be affixed to the structural bar 251. The outer tube cover 28, rubber plug 27, inner tube cover 26, and structural bar 251 can be fixed together by screws. The outer wall of the rubber plug 27 forms an extrusion fit with the inner wall of the outer tube 24, that is, the rubber plug 27 is tightly plugged into the end of the outer tube 24, thereby achieving installation of the structural bar 251 within the outer tube 24. In this embodiment, the rubber plug 27 is cylindrical and creates a certain distance between the inner tube cover 26 and the outer tube cover 28. This allows for electrical isolation and provides a vibration-damping buffering effect.

[0057] Specifically, in order to improve the light uniformity of the LED light bar 25 on the entire outer tube 24, the LED light bar 25 should be kept at the axial center position of the outer tube 24; Figure 7-9 The lamp tube module 2 also includes a plurality of positioning brackets 29, and the positioning bracket 29 includes a first support portion 291 and a second support portion 292 located outside the first support portion 291. The first support portion 291 and the second support portion 292 are connected by a maintaining portion 293. The first support portion 291 is sleeved on the structural bar 251, and the second support portion 292 forms an elastic extrusion fit with the inner wall of the outer tube 24.

[0058] In this embodiment, the positioning bracket 29 is an elastic structure formed by bending a metal strip, and the maintaining portion 293 is used to maintain a certain distance between the first support portion 291 and the second support portion 292, more precisely, to maintain the first support portion 291 at the axial position of the second support portion 292; the first support portion 291 is an overall arc-shaped structure to be sleeved on the structural bar 251 (may include being sleeved on the LED light strip 25), and the second support portion 292 is an overall arc-shaped structure to match the circumferential inner wall of the outer tube 24.

[0059] When subjected to vibration, the first buffer pad 115 and the second buffer pad 124 can achieve vibration reduction and isolation between the lamp holder 1 and the lamp tube module 2; the positioning bracket 29 and the rubber plug 27 can achieve vibration reduction and isolation between the outer tube 24 and the structural bar 251.

[0060] It should be noted that the lamp of the present invention can achieve fast docking between lamp holders 1 and lamp tube modules 2 of different models through the standardized design of the first connecting part 11 , the second connecting part 12 , the third connecting part 21 and the fourth connecting part 22 .

[0061] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
